I am uber jealous of their giant display wall, about as jealous as I am of lrvick's display wall. I am just about willing to throw down the money to build my own D:

The writeup doesn't explain much about how they did, or even show a raspberry pi in use. Is it xdmx? Are they using one rpi per display to turn the display into a network-display? Are they using something like a Matrox TripleHead2Go that emulates one large screen? Does the rpi have enough video memory for that?
